GAS riio nuonn AND COMPRESSOR.

' To all whom it may concern:

"Be it known "that I, EMMANUEL Fr'imx 'AUMONT, a" citizen, of the FrenchRepublic, residing at Paris, Department of the Seine, France, haveinvented certain new and useful Improvements in Gas Producers andCompressors; and I do hereby decl'arethe following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art-to which it 'appertains to make and use the same;

This invention relates to apparatus for making a storing and dispensingmedium for "carbonated beverages, andhas for its obj'ectxtheprovision-of an apparatus having the novel 'features of constructlon.and operation, as-hereinafter described.

The invention is illustrated in the accompanying drawings, in whichFigure l is a broken view, partly in section, of the improved apparatus,showing one form of means for admitting. conibustion products to'theinjector; Figs. 2 and 3,

incombinatiomshow an apparatus in which a modified form of the means foradmitting the combustion products'is used; and Fig. 4 is a-verticalsection'takemon the longi- 'tudinal center line of the constructionshown in Fig. 2.

Beverages, such as beer and the like, rapidly lose their quality whensubjected to the action of air, while the preservation of such liquidsis assured if they are kept under pressure by meanspf. a medium, such ascarbonic acid gas. The mixture .of nitrogen and carbonic acid gas formedby combustion hasall .the advantages "of carbonic 'acid gas alone,besides costing very little as, compared with the relativehigh cost ofcarbonic acid gas. I

The present apparatus is especially designed forjmaking and storingunder pressure in a simple manner, a mixture of nitrogen and carbonicacid gas to be used for storing anddispensing beverages. Referring toFig. 1', the compressing reservoir is'shown'at (Z provided with anoutlet 0 controlled by a suitablezvalve m. a The out- ;letcfmaydischarge .the'iliquid contents of the ;reservoir '(Z wherever desired,a tank or being shown for this purposeinto which the -;outlet' pipe 0discharges.- Liquid such as .zwat'er is injected into the compressingreserv01; d by'a suitable injectora interposedin the. inlet 0.

mitted to the'burner through a chamber 00,

in which is located a diaphragm u in prox- The diaphragm u so dividesthe chamber as to provide a. lower compartment 'w in communication withthe reservoir d by means of a conduit 0. A by-pass 2 serves to con-'stantly supply a small pilot-light with fuel,

said pilot-light being located adjacent the burner screen 9. A conduit 8places the top of the burner 79 in communication with the inlet a of thereservoir, the communication between said inlet and the conduit 8 beingcontrolled by a check-valve b. A branch conduit 0, having an inlet 0, ispreferably provided, for the purpose hereinafter described. Theoperation of such construction is as follows: The liquid admitted to thereservoir (Z through the injector entrains the products of combustionproduced by the burner and forces the mixture of the liquid and theburner gases into the reservoir (Z.

gases separate from the liquid in the reservoir J and rise to the toppart thereof, where they are compressed and forced through a conduit i.into the storing tank or receptacle -70, a check-valve j being providedto prevent return of the gases to the reservoir (Z. The above actiontakes place only when the valve m is open, and the pressure in thereservoir d thereby relieved to a certain ex- This permits the injectionof the valve 6 and the admission of the gases. as

- hereinbefore described. There is placed in the upper portion of thereservoir (Z, a float Yvalve g which closes when the liquid in thereservoir reaches a predetermined level Prior to the closing of theiioat valve 9, the gases accumulating in the reservoir (Z are sforced'into the storing tank or receptacle 70, {as above stated. When the valvemis closed,

Fig. 1.

the injecting action continues until the pressure in the reservoir d issubstantially equal to that of the admitted liquid, at which time theinjection ceases and the valve 6 closes. The pressure in the reservoircl then serves to lift the diaphragm u and cuts olf the supply of fuelto the nozzle 25, thereby extinguishing the burner; W hen the pressurein reservoir cl is lowered by opening the valve on, the diaphragm alowers and the pilot-light adjacent the screen 9 ignites the burner, andthe operation of the parts, as hereinbefore described, is repeated.

In the form of the apparatus shown in Figs. 2 and 3, the injector acommunicates with the lower compartment to of the chamber 50, the twobeing separated by a diaphragm, as in the construction shown in Theburner and its operation are similar to that shown in Fig. 1, exceptthat above the burner is disposed a chimney 8 having at its upperextremity, a domeshaped closure 1 which fits the chimney s loosely. Thegases pass from the domeshaped closure 1 through the passages 2 to areservoir 3. A conduit 2" provided with a coil 71 and check valve 9places the reservoir 3 in communication with the conduit 42,hereinbefore described. WVhen the valve m is closed, the pressure in thereservoir d causes the liquid admitted through the con duit c to rise inthe conduit '0, and thereby lift the diaphragm between the chamber a;and'the compartment '10, thus serving to cut off the supply of fuel tothe burner. A portion of the liquid in the conduit '0 passes through theshunt passage 2" and serves to close'the check-valve 9. When the valve mis opened, the diaphragm associated with the chamber :0 and compartment'10 lowers and the pilot-light ignites the burner which produces thegases that are drawn through the chimney s, closure 1, openings 2,reservoir 3 and conduit 2" to the injector a. The reduction of pressurein the conduit 2;, resulting from the injection action at a, permits thecombustion products to pass to the injector through the check-valve g.The opening between the dome-shaped closure 1 and the chimney s performsthe same function as the opening at 0, in Fig. 1, to wit, places theinjector and also the burner in communication with the atmosphere, andthereby renders the operation of the injector independent of theoperation of the burner. That is, if the suction of the injector is veryslight, the excess products of combustion will pass through this opening between the dome-shaped closure 1 and the chimney 5, but if thesuction of the injector tends to draw in more products of combustionthan supplied by the burner, air Will be admitted through the openingbetween the dome-shaped closure 1 and the chimney s. The burner isdesigned, however, to furnish the products of combustion in sufiicientquantities to always meet the demand of the injector. and the lastnamedcondition will probably never occur.

Obviously numerous changes and modifications may be made in the detailsof construction without departing from the spirit or scope of'theinvention, as defined in the accompanying claims.

What I claim is 1. Apparatus of the kind described, comprising areservoir, an injector associated therewith through which a liquid maybe injected into said reservoir, a burner,means associated with saidinjector to admit products of combustion of said burner to the injector,and an outlet valve associated with the reservoir.
